Real Insect Paperweight - Green Rose Chafer Beetle

Brand: Samfe

This attractive handcrafted paperweight is made with a real insect, farm raised to ensure quality. The beetle is permanently embedded in LuciteÂ® acrylic resin to guarantee durability and clarity. Acrylic resin, or Polymethyl methacrylate (PMMA,) is lightweight, has high transparency and high weather resistance: it does not easily turn yellow or crumble by sunlight. PMMA also does not shatter but instead breaks into dull pieces, which makes it popular in a variety of uses: For example, transparent windows in aquariums, signboards, cell phone display screens and vehicle taillights.

Wimshurst Machine produces 5 inch sparks @ 250,000 Volts! Straight from the box, our Classic Wimshurst Machine is ready to go...screw in the handle, lower the collection arms and literally start cranking out 250kV. Our Active Statics Classic Wimshurst Machine was designed to be something James Wimshurst, the 19th century developer of these iconic machines would recognize. Thats why we call this our "Classic Wimshurst Machine". Our adjustable spark gap gives you the option producing smaller, but more frequent (up to a several per second) discharges or less frequent but enormous, 5+ inch sparks (1 with every few rotations of the handle). Although classic in appearance, our Wimshurst Machine features 12" rotating discs made of tough, clear PMMA polymer, 17 times stronger than glass. Our ultra efficient static charge collecting brushes feature conductive polymer construction and will not scratch discs. We designed our Leyden jars (capacitors) our be long and thin, resulting in extra long, but low current sparks.

The Science Source Bottle Rocket Launch Pad

This launch pad is a stable, lightweight, support pad designed to be used in conjunction with the single bottle rocket launcher (sold separately- ASIN B008AK6600) on hard surfaces such as driveways and parking lots or when the ground is too soft or muddy. The pad design is simple but effective and is constructed of durable plastic that measures 12â€ x 9â€. This launch pad features a molded â€œexhaustâ€ chute for the ejected water along with a nonslip bottom. Additional support may be used if needed to add stability to the launch pad such as sand bags or weights. Operating instructions and guidelines are included. Educational products, manipulatives, and kits incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use educational kits, products, and manipulatives alongside math, science, literacy, and STEM curriculum to demonstrate concepts and real-world applications through hands-on activities.
